SN74F244DBR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74F244DBR is an octal buffer and line driver manufactured by Texas Instruments. It features tri-state outputs and operates within a supply voltage range of 4.5 V to 5.5 V. The device utilizes Schottky TTL logic technology for high-speed performance. It is housed in a 20-pin SOIC surface-mount package with a standard width of 7.50 mm. The component supports unidirectional data flow and includes two independent control inputs for output enablement.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Octal configuration providing eight non-inverting buffers or line drivers on a single integrated circuit
• Tri-state outputs allowing multiple drivers to share a common bus without electrical interference
• Schottky TTL construction ensuring fast switching speeds and reduced power consumption relative to standard TTL

Buffers, Drivers, Receivers, Transceivers Applications

• Memory address buffering for microprocessor systems
• Clock distribution networks requiring signal regeneration
• Bus-oriented transmissions in industrial control architectures

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DBR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the Schottky TTL input levels are compatible with the driving source logic family, as these devices do not tolerate voltages exceeding the specified maximum ratings. Ensure the SOIC-20 footprint matches the target PCB design guidelines.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high-speed digital isolation is required between different system segments. The Schottky technology offers superior speed compared to standard 74-series logic but requires careful attention to noise margins. Consider the thermal dissipation characteristics of the SOIC package if operating near maximum temperature limits or under heavy capacitive loads.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Texas Instruments 74F series, which represents a high-speed variant of the industry-standard 7400 logic families. The 244 designation specifically identifies the octal buffer topology with tri-state capabilities. This series is widely utilized in legacy and modern digital designs requiring robust signal integrity and fast propagation delays.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct replacements include the SN74F244D (tube) from Texas Instruments. Cross-manufacturer equivalents such as the MC74F244AN from onsemi may be considered, provided pinouts and electrical specifications align with the original design requirements.
